Input validation vulnerability in Advanced Database Cleaner 3.1.3

The Advanced Database Cleaner plugin for WordPress has a security issue where it can be manipulated by hackers through a process called PHP Object Injection. This can happen in versions up to 3.1.3, where the plugin does not properly handle input from untrusted sources. This can allow a hacker with administrator access to insert their own code and potentially gain access to sensitive information or delete important files from the website. If the website has additional plugins or themes with similar vulnerabilities, it could make the situation even worse.
